Letters Patent No. 61,210, dated January 15, 1367.

IMPROVEMENT IN STEAM GENERATORS.

TO WHOM IT MAY OONCERN:

Be it known that I, MARTIN C. KrLGoRE, of Washington, iuAthe county ofWashington, and State oi Iowa, have invented a new and valuableImprovement in SteamB'dilers; and I do hereby declare that the followingis a full, clear, and .exact description f the construction fandOperation of the same, referencebeing had to the annexed drawings,making apart of this specificaticmand to the letters and figures-ofreference marked thereon.

The object of my invention is to provide means for raisingr steam withgreater dispatch and i'or superheatingl and economizing such steam moreeifcctively than has been accomplished by any device heretofore known.To

l this end I construct a boiler in two sections, the lower o'ne of whichextends down and around the'fnrnace, as shown on Figure l of thedrawings. I call the upper sect-ion A and the lower section B. Thesesections are united by anges which extend outward from each, as shown atC, and which are fastened together by means of bolts, nuts,

and screws, :1nd suitable packing of lead or gum. A ilange, D, extendsupward from section B inside of section A, when the two sections areunited. It serves as a rest and. support for the joint C, and also aidsin packing the same securely. In, addition to the grate, my furnace isprovided with a square ilue-box marked E. This flue-boxsi-ts on the topoi' the furnace, and has in it a suitable number of tubes that extend`from side to' side and cross eachother at right angles, as shown onFigure 2. In constructing this flue-box, careshould be taken not toincrease the number of tubes so as to interfere with the draught of thefurnace. Both sections of my boiler have a cylindrical form, and sectionA encloses the uebox above described. My boiler is designed to set in anupright position only. Section A of my boiler has an aperture at'- itstop corresponding in size to an aperture or opening on the top of saidilue-box, to which it is attached by means of-bolts, nuts, and screws,and suitable packing, as shown at G,rou iig. 1. On the inside of sectionA, and attached thereto, I placepockets or receivers for holding steam,marked II. These' pockets arc usually four in number, and are placed oneon each side of the {lue-box in the form and shape represented on iig.2. I attach to these pocketsfaucets or escape-cocks, marked I, for thepurpose of letting oil' the condensed steam or water that may accumulatetherein. At the top of the boiler, and supported by the tubeshereinafter described, Iplace a cylinder or domein lwhich the steam issuperheated. It is marked K on the drawings. A. tube marked L leads fromeach of the pockets H into the upper end of this dome,and other tubesmarked M lead into the lower end of the wsame from the top of the boilerproper. The steam pipe is attached to a tube on the top of the domemarked N,'a.nd the chimney is adjusted on tlieuftopl of theboilerm-utside of the tubes L and M.

My devicelgis operated 'in the same manner as other ,uprightsteam-*boilers Its advantages con-sist in an upright draught for thetire; in presenting a greatwater surface to the action of the tire inproportion to the amount of water being used; in economizing andsuperheating steam by means of the pockets H and the dome Kand tubes Land M; in ease and durability ofpacking by means of the ilanges G and D,and lu aiording ready means for cleaning by being constructed insections that can be readily taken apart.

What I claim as my invention, and desire to secure byLetters Patent, is-

1. The pockets I-I, 'constructed substantially as and for the purposesspecified.

2. The'domc K,.in combination with the tubes L and M, constructed andoperatingsubstantially as setforth.

3. A steam boiler, having sections and B, flanges G and D, flue-bex E,and dome and tubes and pockets as described, constructed, combined, andarranged substantially; as herein speoiied.
